Change to zstd compressed instead of gz-compressed tarballs. zstd
compresses 7-8 times faster and decompresses 2-3 times faster.
This change also make sharing tarballs between different branches
possible, because OpenWrt 25.12 uses zstd as default.

KERNEL_MAKE_FLAGS passes arguments to 'make'
and not to the compiler which is probably
what was intended.
This solves a compilation issue on the
Broadcom platform.
The inclusion of bcm-kernel-toolchain.mk cannot be conditional since
CONFIG_TARGET_brcmbca is not defined when package metadata is being
generated. Instead make it optional in case broadcom feed is absent.
